Twelfth Amendment - Election of President and Vice President
Original Text
The Electors shall meet in their respective states and vote by ballot for President and Vice-President, one of whom, at least, shall not be an inhabitant of the same state with themselves; they shall name in their ballots the person voted for as President, and in distinct ballots the person voted for as Vice-President, and they shall make distinct lists of all persons voted for as President, and of all persons voted for as Vice-President, and of the number of votes for each, which lists they shall sign and certify, and transmit sealed to the seat of the government of the United States, directed to the President of the Senate;—The President of the Senate shall, in the presence of the Senate and House of Representatives, open all the certificates and the votes shall then be counted;—The person having the greatest number of votes for President, shall be the President, if such number be a majority of the whole number of Electors appointed; and if no person have such majority, then from the persons having the highest numbers not exceeding three on the list of those voted for as President, the House of Representatives shall choose immediately, by ballot, the President. But in choosing the President, the votes shall be taken by states, the representation from each state having one vote; a quorum for this purpose shall consist of a member or members from two-thirds of the states, and a majority of all the states shall be necessary to a choice. And if the House of Representatives shall not choose a President whenever the right of choice shall devolve upon them, before the fourth day of March next following, then the Vice-President shall act as President, as in case of the death or other constitutional disability of the President.

In Plain Language
The Twelfth Amendment fixed a fatal flaw in the original Electoral College: electors now cast separate ballots for President and Vice President. This allows running mates to campaign as a team rather than compete against each other. If no candidate wins an Electoral College majority, the House chooses the President (one vote per state, regardless of population) and the Senate chooses the Vice President.
The Twelfth Amendment is only one part of the modern presidential election framework. The 20th Amendment (1933) moved inauguration from March 4 to January 20, shortening the lame-duck period. The 22nd Amendment (1951) imposed a two-term limit. The 25th Amendment (1967) addressed presidential disability and the succession process. Reading the Twelfth Amendment alone gives an incomplete picture of how presidential elections actually work today.
Historical Significance
Electors now vote separately for president and vice president. The original system produced a tie between Jefferson and his running mate Aaron Burr in 1800, throwing the election to the House for 36 ballots. The amendment was ratified on June 15, 1804.

Historical Context
The original Constitution had electors cast two undifferentiated votes: the top vote-getter became President, the runner-up became Vice President. The 1796 election immediately revealed the flaw—rivals John Adams (Federalist) and Thomas Jefferson (Democratic-Republican) were paired in an unworkable administration. The 1800 election made it catastrophic. Jefferson and his running mate Aaron Burr tied with 73 electoral votes each, even though everyone understood Jefferson was the presidential candidate. The deadlock threw the election to the House, which voted 36 times over six days before Jefferson won on February 17, 1801. Hamilton, who preferred Jefferson over Burr, worked behind the scenes to break the deadlock—deepening the enmity that would end in their 1804 duel.
Congress proposed the Twelfth Amendment by the required two-thirds margins and the states ratified it on June 15, 1804—just before that year's election, in which Jefferson won decisively over Charles Pinckney.
The amendment left other structural problems unaddressed. The original March 4 inauguration date created a four-month lame-duck window—long enough for a defeated president to do serious damage or for a foreign power to exploit the transition. The 20th Amendment (1933) shortened that gap. Presidential disability and vice-presidential vacancy remained undefined until the 25th Amendment (1967).
How This Shows Up Today
The Twelfth Amendment structures every presidential election. In Chiafalo v. Washington (2020), the Supreme Court ruled 9-0 that states can fine or replace "faithless electors" who vote against their pledged candidate. Thirty-eight states now bind electors by law. The amendment's "habitation clause" bars electors from voting for two candidates who both live in the elector's home state. In 2000, Texas voters challenged Dick Cheney's eligibility because he lived in Dallas while running with George W. Bush. Courts ruled Cheney had established Wyoming residency four days before his nomination, avoiding a constitutional crisis over Texas's 34 electoral votes. The contingent election process—House choosing the President if no majority—hasn't been used since 1824 but remains a live constitutional mechanism.
